However, scientists at the Department of Medicine III and the Section for Science of Complex Systems at MedUni Vienna have demonstrated that these risks can now be practically eliminated by using optimised, personalised therapy.http://medicalxpress.com/news/2016-11-personalised-therapy-cancer-diabetes-patients.html

Working at the interface of chemistry and neuroscience, Berkeley Lab chemist Christopher Chang and his research group at UC Berkeley have developed a series of fluorescent probes for molecular imaging of copper in the brain. Speaking at the recent national meeting of the American Chemical Society in New Orleans, he described the challenges of creating and applying live-cell and live-animal copper imaging probes and explained the importance of meeting these challenges.http://medicalxpress.com/news/2013-05-copper-brain.html
NeuroscienceMon, 27 May 2013 08:20:01 ESTnews288859431Can new plasma-based biomaterials speed healing of injured tissues?Platelet-rich plasma (PRP) derived from blood contains growth factors and other bioactive molecules that promote healing at sites of tissue injury. However, it is difficult to deliver and retain these molecules at a target site, and clinical results have proven to be mixed – until now. A new solid form of bioactive plasma-based biomaterials, known as PBMs, can accelerate tissue healing. Not only are PBMs easier to work with, inexpensive to produce, and safe to use, they are available as off-the-shelf products. All of these promising advantages, and the potential to use PBMs to enhance healing of difficult-to-treat connective tissue injuries affecting cartilage, tendons, and ligaments, contribute to their unique possibilities as described in the article "Biologically Active Blood Plasma-Based Biomaterials as a New Paradigm for Tissue Repair Therapies," by Smith et al. in Disruptive Science and Technology.http://medicalxpress.com/news/2013-04-plasma-based-biomaterials-tissues.html
